Hi Chris.
I revisited the old mailing list entries (4 in 1 Thread) and didn't find
any real arguments for or against git but "it would slow down
development because I don't know git, yet".
So I created a list of the advantages git provides so everyone has a
good basis for the discussion tomorrow:
-----
Git:
- better access, easier to join development for new developers
- work on their own repository
- push to shared repository when ready
- faster merge
- records your commit history as a directed graph of commits, it's
easy for it to automatically figure out the best merge base to do a
three-way merge [*1] with
- branching much faster
- example - one of my projects:
- branching with git (git branch) of a simple project takes
less than a second
- branching with svn (svn copy and svn switch) of a simple
project takes about 13 seconds
- *distributed*, not centralized, version control system
- users work locally in their branches, check in offline and later
merge the changes back to the master branch
- does not depend on a centralized server, but does have the
ability to synchronize with other git repositories -- to push and pull
changes between them
- concept of master or centralized repository as in subversion but
the repository maintained by the project owner still is considered to be
the master
- many developers work in different countries simultaneously
- security:
- immediately after the repository clone, there is basically no
information about that project that the server you cloned from has that
you do not have (including ALL changes and revisions)
- every person working on your project has what is essentially a
full backup of the project data
- faster everything:
- when you create a branch in Git, it does so locally and it
happens very fast
- optimized for complex diffing, complex merges, making branches,
being robust
- very efficient storage
- example: entire history of the 2.6 linux kernel is only 1/2
the size of the current checkout of it

For the agenda we have so far
1) Architecture discussion: gstreamer composer service
2) GIT vs. SVN
3) Review of current 1.3 issues
4) Release timing of 1.3
Any other items?

I hope whoever is bringing up GIT v. SVN revisits the discussion that
already happened on list (though some happened in IRC) before the
meeting so we don't just rehash old points.
